Question 5 of 552
In 6PE and 6VPE networking, no VPN instance needs to be created on PEs.
Correct Answer: B

In 6PE and 6VPE networking, VPN instances typically need to be created on PEs (Provider Edge routers). For 6VPE (IPv6 VPN Provider Edge), VPN instances are necessary to isolate and manage the IPv6 VPN traffic. These instances, known as Virtual Routing and Forwarding (VRF) tables, are used to store and process the routes for different VPNs. Therefore, the statement that no VPN instance needs to be created on PEs is false.
